HINGE FOR GATE-FRAMES.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed January 13, 1908. Serial No. 410,656.

To all whom it may concern:

Be it known that I, ALEXANDER Soo'r'r MAGKEY, a subject of the King ofGreat Britain, residing at the city of Ottawa, in the county ofCarleton, in the Province of Ontario, in the Dominion of Canada, haveinvented certain new and useful Improvements in Hinges for Gate-Frames,of which the following is a specification.

My invention relates to improvements in hinges for gate frames,particularly those constructed of hollow tubing, and the objects of myinvention are to provide a simple but rigid form of hinge which willexclude the water from the interior of the pipe and in which there willbe as little opportunity as possible for the water to enter between thefixed and rotary member, the details of the invention being describedfully in the accompanying specifications and drawings.

In the drawings, Figure 1 is a longitudinal sectional view through thehinge. Fig. 2 is a section on the line 22, Fig. 1.

In the drawings, like characters of reference indicate correspondingparts in each figure.

Referring to the drawings, 10 and 11 represent the tubular members,which will, together with other members, form a gate frame of anysuitable shape or character. These members are held in alinement witheach other and are rigidly connected by an interior cylindrical member12 having a plurality of peripheral annular grooves 13 formed in eachend, and into which fit corresponding corrugations leformed on theinterior of the members 10 and 11. In practically forming the joint, thesaid corrugations 14 are preferably formed in the members 10 and 11after they are placed in position over the interior member, the saidcorrugations being conveniently formed by means of an ordinary pipecutting tool, whose cutting element has been replaced by a disk having arounded periphery, which will roll the corrugations into the pipe. Theresult of this operation is to very firmly and effectually lock theouter members to the interior members.

To complete the hinge, the bracket memher A is provided having a sleeve15 formed at the end thereof, which fits over the interior member 12 inthe space between the two members 10 and 11 and has faces 16 and 17 onthe edge thereof, which abut and fit closely to the ends of the members10 and 11. The result of this is to form a water-tight joint between thetwo members. The bracket member A may be secured to any fixed supportand in this case, the gate frame may swing on the bracket.

In case where the members 10 and 11 on the gate frame extend verticallyeither of the faces 16 or 17, will form aneffectual bearing to givevertical support to the frame.

As many changes could be made in the above construction, and manyapparently widely different embodiments of my invention, within thescope of the claim, could be made without departing from the spirit orscope thereof, it is intended that all matter contained in thesespecifications and drawings, shall be interpreted as illustrative andnot in a limiting sense.

What I claim as my invention is:

A hinge for gate frames, including an interior cylindrical member formedwith peripheral grooves at each end, tubular end members having interiorannular corrugations in engagement with the grooves on the interiormember, the said members being nonrotatably connected to said interiormember, a bracket member having a sleeve rotatably mounted on theinterior member between the end members and being adapted to be securedto a fixed support, and having the ends of the sleeve abutting andfitting closely to the ends of the end members, whereby a water-tightjoint will be provided, and support given to the end members when theyare in a vertical direction.

Signed at Ottawa, this 7th day of January, 1908.
